PROBLEM TO BE SOLVED: To provide an adhesive for a laminate sheet excellent in initial adhesion to a film after curing and in a curing rate during the production of a laminate, and excellent in long-term hydrolysis resistance under high temperature.SOLUTION: An adhesive for a laminate sheet includes a urethane resin obtained by mixing an acrylic polyol and an isocyanate compound together. The acrylic polyol is produced by polymerizing polymerizable monomers and has a glass transition temperature from -20 to 20°C. The polymerizable monomers include a monomer having a hydroxyl group and other monomers, and other monomers include acrylonitrile. The isocyanate compound includes both an isocyanate having no aromatic ring and an isocyanate having an aromatic ring. On the production of a laminate, the adhesive for a laminate sheet is excellent in initial adhesion to a film after curing, in a curing rate, and in long-term hydrolysis resistance under high temperature. |
